Three stone and side stone engagement rings by Lisa Robin in tapered baguette, round, oval, emerald cut, and mixed-shape designs

Three Stone Engagement Rings

Designed by Lisa Robin: Three Stone and Side Stone Engagement Rings, Made to Order

A three stone engagement ring centers a diamond between two flanking diamonds — three diamonds that traditionally represent past, present, and future. A side stone engagement ring follows the same idea, with one or more accent diamonds set on each side of the center. Both arrangements share a structural philosophy: the center diamond leads, the side diamonds support and frame it. Lisa Robin three stone and side stone engagement rings are hand-crafted to order in 3-4 weeks, with your selected center diamond, side diamond shape, metal, and design refinements. Whether you arrive ready to order online or want Lisa to guide you through a private design appointment, both paths lead to the same craftsmanship.

      What Defines a Lisa Robin Three Stone Engagement Ring

      Each Lisa Robin three stone engagement ring is built around the relationship between three diamonds — the center and the two flanking it. The Devon Three Stone Diamond Engagement Ring centers a diamond between two tapered baguette diamonds, the architectural three stone arrangement that prioritizes clean lines and structural balance. The tapered baguettes guide the eye toward the center diamond while contributing their own brilliance through long, mirror-like step facets. The proportions are deliberate: each baguette is calibrated to flatter the center without competing with it.

      Your ring is hand-crafted to order at our New York workshop after you select your center diamond, side diamond shapes, metal, and any refinements. Designed in Dayton, Ohio. Made in the USA.

      Any three stone or side stone design can be refined before crafting begins: change the side diamond shapes (tapered baguettes, rounds, pears, half-moons, trapezoids), adjust the proportions between center and sides, modify the band width, or coordinate the design with a future wedding ring. Custom three stone designs from scratch are also available — the design appointment is the path for that. Pricing for any refinement is shared transparently before approval.

      The Lisa Robin Global Diamond Collection

      Lisa Robin sources from a global inventory of millions of natural and lab grown diamonds — selected specifically for engagement ring quality.

      You can browse and select your center diamond and side diamonds online or during a private design appointment. Either way, you see the full specifications — carat, color, clarity, cut, and certification details — along with a video of the actual diamond before you approve it. Lisa is available to guide you through the selection by phone or video appointment if you'd like help, starting at the highest quality and adjusting where it matters least to the eye if budget is a factor.

      Available in carat sizes from 0.50 carat through 5+ carats and in every standard shape: round, oval, cushion, emerald cut, pear, princess, marquise, asscher, radiant, and rose cut.

      Three Stone and Side Stone Engagement Ring Types in This Collection

      Tapered baguette three stone centers a diamond between two long, narrow tapered baguette diamonds. The Devon Three Stone Diamond Engagement Ring is Lisa Robin's signature tapered baguette three stone design — architectural, balanced, and unmistakably classic.

      Round side stone places one or more round brilliant diamonds on each side of the center. Round side diamonds add fluid, continuous brilliance and pair beautifully with round, oval, or cushion centers.

      Pear and half-moon three stone arrangements use shaped diamonds that hug the silhouette of the center. Pear sides curve outward toward the band; half-moon sides create a softer, rounded transition. These are most often custom-designed to specification.

      Mixed-shape three stone pairs different diamond shapes for visual contrast — an emerald cut center with round sides, an oval center with tapered baguettes, or a cushion center with trapezoid sides. Mixed-shape designs are typically created during a private design appointment.

      Vintage style three stone adds milgrain detail, scalloped edges, or filigree references to any of the arrangements above for an heirloom feel.

      Choosing Your Three Stone or Side Stone Engagement Ring

      Side diamond shape. Tapered baguettes give the most architectural, geometric look. Round brilliants give the softest, most fluid sparkle. Pear and half-moon shapes follow the curve of the center. Trapezoids and shield cuts create a more sculptural transition. Each side shape changes the character of the entire ring.

      Proportions. The relationship between center diamond size and side diamond size is the design's most important variable. Larger sides create a more substantial, balanced silhouette. Smaller sides emphasize the center. Lisa guides this choice during the design process based on your center diamond and your aesthetic.

      Symbolism. Three stones traditionally represent past, present, and future. Side stones can symbolize partnership, support, or the people who shaped your relationship. The symbolism is yours to define — many couples choose three stone or side stone designs specifically because the meaning matters to them.

      Metal. Three stone and side stone engagement rings are available in 14K yellow gold, 14K white gold, 14K rose gold, and platinum. White metals emphasize the brilliance of every diamond; yellow and rose gold create warmth around the center.

      Wedding ring coordination. Three stone and side stone engagement rings pair with straight bands, contoured bands, or diamond bands. Plan the wedding ring during the engagement ring design.

      Frequently Asked Questions About Three Stone and Side Stone Engagement Rings

      A three stone engagement ring features a center diamond flanked by two side diamonds. The arrangement traditionally symbolizes past, present, and future — the three diamonds representing the relationship's history, current commitment, and shared future. Three stone designs include tapered baguette sides, round sides, pear or half-moon sides, and mixed-shape combinations.

      A three stone engagement ring uses one center diamond and two flanking diamonds — three diamonds total. A side stone engagement ring features a center diamond with one or more accent diamonds on each side, often more than three diamonds total. Three stone is a specific subset of side stone designs. Both arrangements share the structural idea of side diamonds supporting the center.

      Yes. Side diamonds extend the visual width of the ring and draw the eye across the design, making the overall arrangement read larger than a solitaire of the same center diamond size. Tapered baguette sides have the most pronounced size-extending effect because of their long, narrow profile.

      Three stone engagement ring settings in this collection start at $2,695. Paired with a 1 carat lab grown diamond center, three stone engagement rings start at approximately $3,595. Final pricing depends on the center diamond you choose, the side diamond shape and size, and your metal selection. We discuss diamond selection during the design process and share pricing transparently before crafting.

      Each three stone engagement ring is made to order and ships in approximately 3-4 weeks from design approval. Custom three stone designs created from scratch typically take 3-4 weeks from final design approval, with the design phase preceding crafting.

      Yes. Mixed-shape three stone designs are popular and beautiful — emerald cut center with round sides, oval center with tapered baguettes, cushion center with trapezoid sides, or other combinations. Mixed-shape designs are typically created during a private design appointment so Lisa can guide proportion and balance decisions.

      Yes. Choose your center diamond shape and quality, your side diamond shapes and arrangement, your metal, and refine the proportions, band width, prong style, and wedding ring coordination. For mixed-shape designs or fully custom three stone arrangements, book a private design appointment with Lisa — virtual, by phone, or in studio.
